International ClassH04R 025/00Foreign Application Priority Data1988-05-06 DEAbstractA control device for a hearing aid is inconspicuously held by a hearing aid user, such as in the palm of the hand, and includes a vibrator which emits a remote control signal at a frequency outside of the audible range of human hearing, and the hearing aid worn in the ear of the user has circuitry responsive to these remote control signals. The remote control signals are transmitted via the skeleton of the hearing aid user by transcutaneous coupling of a contact surface of the control device. The hearing aid includes a transducer for converting the received remote control signals transmitted via the body of the wearer into electrical signals for controlling at least some of the components of the hearing aid. The remote control signal may be coded, in which case the hearing aid will also include a recognition circuit for decoding the received signal. | |
